The refrigerator with auxiliary cooling device is disclosed herein.Auxiliary cooling equipment can comprise the heat accumulating of such as phase-change material (PCM) etc., and it stores heat energy at normal operation period, and for refrigerated compartment between turnoff time.Auxiliary cooling equipment (heat accumulation equipment) can comprise the structure of the heat exchange efficiency improved between cold-producing medium and the evaporimeter of refrigerator.
Usually, refrigerator comes cooled interior space thus the household electrical appliance of the perishable commodities of freezing or chilled food or other type by using working fluid (cold-producing medium) to absorb heat.Working fluid can circulate in refrigerant circuit, and refrigerant circuit can comprise compressor, condenser, expander and evaporimeter, in order to cool room in refrigerator.Compressor can be arranged in the lower rear portion of cabinet, and evaporimeter can such as be arranged on the rear wall of the refrigerating chamber arranged in refrigerator, and is operable as and absorbs heat from refrigerating chamber.
At normal operation period, when power supply can be used for driving compressor, cold air continues supply, to maintain the temperature in refrigerator by refrigerant circuit.But, if refrigerant circuit because of such as power-off, power failure, compressor fault or and so on reason and can not run, then the temperature in refrigerator may raise.
Particularly, the temperature that wherein food easily occurs in corrupt refrigerating chamber can raise rapidly.The food stored in refrigerating chamber raises more responsive to temperature, and may be more perishable than the food stored in refrigerating chamber.Therefore, as this paper generalized description and the refrigerator implemented (such as, have a power failure or power failure during) when refrigerant circuit cannot be run prevents or the temperature that slows down in refrigerating chamber raises.In addition, refrigerator can comprise the housing for phase-change material, and this housing can protect phase-change material between the refrigerating chamber normal operating period, and improves performance by increasing with the contact area of the evaporimeter be arranged on wherein.
Describe refrigerator in detail below with reference to accompanying drawings.Now can in detail with reference to specific embodiment, its example can be shown in the drawings.In the conceived case, identical Reference numeral can be used to refer to same or analogous part in all of the figs.
Fig. 1 is the stereogram of refrigerator.Refrigerator 1 can comprise refrigerator cabinet 10, evaporimeter 20 and door 15.Refrigerator 1 is included in the storeroom wherein arranged, and refrigerant circuit can be used to maintain the temperature in storeroom, thus stores perishable commodities wherein.Door 15 can be attached to cabinet 10, to provide the entrance entering storeroom.
Refrigerator cabinet 10 can have unlimited front portion, and storeroom can be arranged on wherein to preserve food.Refrigerator cabinet 10 can be formed as having one or more storerooms that can remain on assigned temperature.Such as, the refrigerator being configured to family expenses can be divided into internal temperature and maintain refrigerating chamber 11 under 0 DEG C (32 °F) and internal temperature and to maintain on 0 DEG C and lower than the refrigerating chamber of assigned temperature (such as, about 10 DEG C or 50 °F).
Door 15 can be simple gate as shown in Figure 1, if or need, two or more door can be comprised.The quantity of door 15, size and structure and/or aesthsticly can be considered determine based on the function expected.

Cold-producing medium can liquefy in condenser and compressor, and can evaporate to absorb latent heat in evaporimeter 20, thus reduces the temperature of storeroom.In other words, in evaporimeter 20, the internal heat with storeroom is performed.In order to improve heat exchange efficiency, the surface of evaporimeter 20 is formed as not flat-shaped (groove or protrusion).The surface of the evaporimeter 20 shown in Fig. 1 can be formed as uneven, to widen the surface area of evaporimeter 20.
Refrigerator 1 can be divided into direct refrigeration-type and indirect refrigeration formula according to the method transmitting cold air to storeroom.In indirect refrigeration formula, fans drive and force circulating cold air, thus scatter cold air.Indirect refrigeration formula is typically in large-scale refrigerator.In direct refrigeration-type, do not use fan, evaporimeter 20 can embed in the enlarged regions of wall, to transmit the heat of evaporimeter 20 directly to the storeroom of refrigerator 1.Direct refrigeration-type is typically for small refrigerator (such as, kraut refrigerator, kim-chirefrigerator).
Compared with indirect refrigeration formula, in direct refrigeration-type, internal temperature can keep homogeneous, is not easy to change.Therefore, direct refrigerating type refrigerator can have the advantage of the taste preserving various food, is not easy to change because its internal temperature can keep homogeneous.Direct refrigerating type refrigerator also can manufacture less noise, and consumes less electric power, because it need not drive fan.
Evaporimeter 20 can be formed at one or more wall surfaces of refrigerating chamber 11.When the quantity of the wall surface installing evaporimeter 20 increases, refrigeration can be strengthened.Refrigerator is as shown in Figure 1 direct refrigeration-type.Here, evaporimeter 20 can be arranged in the top surface of refrigerating chamber 11, basal surface and both side surface.

In the case, PCM housing 35 between refrigerating chamber 11 and refrigerating chamber 12, and can be able to be arranged on refrigerating chamber 12 side of evaporimeter 20 as shown in Figure 2 and Figure 5.In other words, PCM housing 35 can be positioned to carry out heat exchange with evaporimeter 20, to provide the auxiliary cooling to refrigerating chamber 12.In addition, room in refrigerator can be separated into a part for the structure of refrigerating chamber 11 and refrigerating chamber 12 by PCM housing 35.
Next, PCM framework 40 and 45 can be arranged to support PCM housing 30,35, makes its contact evaporator 20, and forms the inwall of refrigerating chamber 11 or refrigerating chamber 12.In the case, PCM framework 40 can be arranged on the top of refrigerating chamber 11 and the surface of both sides.Meanwhile, PCM framework 45 can form the top surface of refrigerating chamber 12.
PCM housing 30,35 can be arranged between PCM framework 40,45 and evaporimeter 20.Between PCM framework 40,45 and evaporimeter 20, can predetermined gap be set, to hold and to support PCM housing 30,35.Therefore, PCM housing 30,35 can prevent PCM housing 30,35 to be out of shape, to guarantee that PCM housing 30,35 keeps in touch evaporimeter 20.Such as, because PCM housing 30,35 can be made up of pliable material, so the shape of PCM housing 30,35 can change state along with PCM and be out of shape.That is, when PCM change state is liquid, more substantial PCM can be gathered in the bottom of housing 30,35 due to gravity.In the case, PCM housing can be separated with evaporimeter 20 near the surface at top.Therefore, PCM framework 40,45 can be arranged to support PCM housing 30,35, to prevent from being out of shape and to keep in touch evaporimeter 20.

Fig. 6 to Fig. 8 is the curve map of the phase transition temperature relative to the time that PCM is shown.Phase transition temperature can refer to the temperature that PCM changes state.When temperature arrives phase transition temperature, the rate of temperature change of PCM is accelerated, and to absorb or to send latent heat, and changes the phase place of PCM.
When refrigerator 1 puts into operation, the phase place of PCM becomes solid-state from liquid state, to absorb the cold air that evaporimeter 20 discharges.When absorbing cold air, the temperature of PCM declines.When reaching the phase transition temperature of PCM, the gradient of the variations in temperature in PCM reduces to some extent.
The phase place of PCM can become solid-state from liquid state in the temperature range of the storeroom of refrigerator 1, or vice versa.In other words, the phase place of PCM can change calmly or in the scope of the internal temperature of refrigerator of setting at user preset, makes can assemble sufficient cold air, to guarantee the phase transformation of PCM.
Meanwhile, the phase place of PCM can in the variations in temperature lower than the temperature outside storeroom.If perform phase transformation in the temperature higher than the outdoor temperature of storeroom, then the temperature of the inside of storeroom must higher than the outdoor temperature of storeroom, and the cold air produced to make the phase transformation of PCM can discharge.Therefore, above-mentioned condition can be satisfied, thus the cold air that the phase transformation making full use of PCM produces.
Fig. 6 is the curve map of the variations in temperature that the phase-change material when the mean temperature of evaporimeter is-11 DEG C (-51.8 °F) is shown.Fig. 6 illustrates phase transition temperature to be the PCM of-12 DEG C of (-53.6 °F) (dotted lines) and phase transition temperature is the variations in temperature of the 2nd PCM of-5 DEG C of (-41 °F) (solid lines).As shown, the gradient of the 2nd PCM reduces at about-5 DEG C of places.The phase place of PCM changes over solid-state near the pact-5 DEG C corresponding to phase transition temperature from liquid state.Scope near phase transition temperature, large energy is stored in PCM.
Meanwhile, the phase place of a PCM changes at the predetermined temperature (such as ,-11 DEG C) lower than the temperature (such as ,-11 DEG C) of evaporimeter 20.When the temperature of phase transition temperature lower than evaporimeter 20, PCM can not become solid-state completely from liquid state.
When the temperature of evaporimeter 20 presses predetermined interval fluctuation, near the mean temperature (such as ,-11 DEG C) of evaporimeter 20, the pattern of the variations in temperature of a PCM and the different of the 2nd PCM.One PCM(-12 DEG C) be fluid or partially liq, the therefore variations in temperature unpredictable of a PCM.By contrast, the 2nd PCM(-5 DEG C) be solid-state, therefore the variations in temperature of the variations in temperature relative evaporation device 20 of the 2nd PCM is more violent.
In other words, when temperature lower than evaporimeter 20 of the phase transition temperature of PCM, PCM, by being solid-state and can not undergo phase transition, can not preserve cold air.The phase place of PCM can in the temperature change higher than the mean temperature of evaporimeter 20.
Fig. 7 is the curve map of the cold air deposit effect of the PCM of the phase transition temperature illustrated according to PCM.The phase place of the PCM that phase transition temperature is-12 DEG C (dotted lines) changed completely in about 400 minutes.The phase place of the 2nd PCM that phase transition temperature is-5 DEG C (solid lines) changed completely in about 250 minutes.The period completing phase transformation is relevant with the ability that PCM stores cold air.The longer corresponding cold air storage capacity in period completed needed for phase transformation is better.Therefore, the PCM with more low transformation temperature can be used.
As with reference to described by Fig. 6 and Fig. 7, can expect that PCM has lower phase transition temperature, but higher than the mean temperature of evaporimeter 20.
Fig. 8 is the curve map of the freezing indoor temperature change generated in case of the phase transition temperature illustrated according to PCM.The climbing speed of the temperature in refrigerating chamber when having PCM than slow when there is no a PCM.That is, as shown, the gradient using the temperature of refrigerating chamber during PCM to raise is less possibly than the gradient of the temperature rising of refrigerating chamber when not using PCM.
When not using PCM, the temperature of refrigerating chamber reaches period of about 0 DEG C can greatly in 42 minutes.When using phase transition temperature to be the PCM of-5 DEG C, this period can greatly in 144 minutes.When using phase transition temperature to be the PCM of-7 DEG C (-44.6 °F), this period can greatly in 310 minutes.When using phase transition temperature to be the PCM of-12 DEG C, the temperature of refrigerating chamber 11 still may can not reach 0 DEG C after 6 hours.Described by with reference to Fig. 6 and Fig. 7, along with the phase transition temperature of PCM reduces, the ability that cold air stores can be improved, and the temperature of storeroom keeps effect also can improve.
As shown in the figure of Fig. 6 to Fig. 8, the phase transition temperature of PCM is more low better.But the phase transition temperature of PCM must higher than the mean temperature of evaporimeter 20.So the lower limit of phase transition temperature must be-10 DEG C (-50 °F) or higher, and this temperature is higher than the mean temperature-11 DEG C of conventional evaporator 20.
And, can select to make temperature under 0 DEG C or 0 DEG C, keep the PCM of predetermined time amount.The operation duration of PCM such as can based on the power failure duration of expection.When such as predetermined time amount be 2 constantly little, the PCM that temperature can be made at least 2 hours to keep under 0 DEG C or 0 DEG C can be used.Therefore, with reference to Fig. 8, phase transition temperature can be used to be the PCM of at least-5 DEG C.In other words, the suitable phase transition temperature of PCM can in the scope of-5 DEG C to-10 DEG C.
